Farmall 140 Need Hyd. Link Arm ?????

If any one could give me the measurments of the lift link I would be very gratful.
Thanks,

In 1951 for the Super-A, the long solid rod that connects the hydraulic unit rockshaft (left side) to the rear, fender-mounted rockshaft was called a 'lift link'. Both were 'special equipment', that is, they were bought separately for the tractor as needed for cultivators and other equipment.
The sliding collar pin has its own hole in the acute-angled 'L' bracket on the left side fender rockshaft and its hole is smaller (if I remember correctly) than the 2-equipment attachment holes on the other leg of the 'L'.
The opposite end of the lift link ends with an 'o' shaped hole to fit into the front hydraulic unit rockshaft attachment point and attaches with a hardened pin held in place with a spring-loaded cover.
I am not familiar with the differences between the 140 and the Super-A, but they are probably very similar.

Can't you straighten your lift link? They often get bent when the user doesn't give the sliding collar enough movement room for some rear mounted equipment, such as a 3-point brush cutter, to rise up as it follows ground contours (Don't ask how I know that). The front hydraulic unit rockshaft is rigid in the position it's set to and it won't back off under pressure, so if something has to give, it's usually the lift link.
You should have a locking collar on the lift link forward of the sliding collar, which you can loosen and move forward to allow a rear mounted implement to freely rise up if need be.
Hope you can find something useful in this description.

The lift link for the SA and 140 are quite differant. For example the front part of the link rod on the SA ends in a flattened part that just has a hole drilled in it. On the 140 it has a large "hook" where the front attaches to the hydraulic unit. The rear of the connecting rod is somewhat differant too, spring is huge on a 140 compared to a SA. Plus if I remember correct there is a square plate between the lift rod and the rockshaft arm. The arm on the 140 is lots thicker than on the SA. You (cant remember) can adjust the lift collar on the 140 but you cant on the SA, its welded in place.

The 140 also has the assist lift spring (differant thing altogether and not even on a SA).

So what someone has done on his is take the hook part and welded it on a pipe (I guess). I dont know what they did on the other end where the spring fits. There is two nuts that go on there to hold that spring.

PS. The bolt that holds the lift arm to the front rocker arm off the PTO is a half inch bolt. I checked on them at Case and they wanted $8 each. I made some myself out of a half inch hex head bolt, cut it and ground down the head. Head of the bolt is kind of rounded so it is pretty easy to do. get a long bolt where you can cut off all the threads.

Read his post again. The bar he has is a replacement that someone welded the old ends on a pipe. Should be a solid rod and pretty good size, about 1"

Least thats they way I took it.
